Abstract

Eine hydrodynamische Kopplungsanordnung ist mit einem um eine Drehachse drehbaren Kupplungsgehäuse ausgebildet, innerhalb welchem zumindest ein durch wenigstens ein Pumpen- und ein Turbinenrad gebildeter hydrodynamischer Kreis sowie zumindest eine Überbrückungskupplung vorgesehen ist, die zur Herstellung einer Wirkverbindung zwischen einem Antrieb und einem Abtrieb für eine Einrückbewegung und zur Aufhebung dieser Wirkverbindung für eine Ausrückbewegung beaufschlagbar ist. Der hydrodynamische Kreis sowie zumindest ein Druckraum sind zur Beaufschlagung der Überbrückungskupplung an jeweils wenigstens einen Strömungsweg angeschlossen, durch welchen der hydrodynamische Kreis oder der zumindest eine Druckraum an wenigstens eine Druckmittelversorgung angeschlossen sind. Zumindest ein während des Betriebszustandes zur Herausführung eines Strömungsmittels aus dem Kupplungsgehäuse dienender Strömungsweg ist mit einer Durchflussvolumen-Reduzierung versehen, die zumindest außerhalb dieses Betriebszustandes für eine wenigstens verzögerte Abnahme des Befüllvolumens im Kupplungsgehäuse sorgt.

Figure imgaf001
A hydrodynamic coupling arrangement is formed with a clutch housing rotatable about an axis of rotation, within which at least one hydrodynamic circuit formed by at least one pump and turbine wheel and at least one lock-up clutch is provided for establishing an operative connection between a drive and an output for an engagement movement to abolish this operative connection for a disengagement movement can be acted upon. The hydrodynamic circuit and at least one pressure chamber are connected to act on the bypass clutch to each at least one flow path through which the hydrodynamic circuit or the at least one pressure chamber are connected to at least one pressure medium supply. At least one during the operating state for the discharge of a fluid from the clutch housing serving flow path is provided with a flow volume reduction, which ensures at least outside of this operating condition for at least a delayed decrease in the filling volume in the clutch housing.
